Asexual Reproduction

Extracts from this document...


Asexual Reproduction: In Asexual reproduction, there is only one parent, and therefore the offspring will be identical to the parent. The offspring will have exactly the same genes as the parent. They are called clones. This is because all the cells in both parent and offspring were formed by ordinary cell division, so they must all have identical genes in their cell nuclei. Asexual reproduction therefore produces no variation. Some plants reproduce asexually, e.g. Potatoes, strawberries and daffodils. A good example of asexual reproduction is a spider plant, if you plant one of these, it will grow into a new plant, and may eventually produce young spider plants itself. The new plants produced by asexual reproduction are just like their parent. If you take a cutting (a cutting is a piece of stem or root, cut from a growing plant) from a geranium, which has pink flowers. The cutting will grow into a geranium, which has pink flowers. This is because the cells of the cutting are identical to the cell of the parent. ...read more.


because there are two parents, the offspring contain a mixture of their parent's genes. The parents have sex organs. The sex organs make sex cells. In male animals, the sex cells are called sperms. The sperms are made in sex organs called testes. In female animals, the sex cells are called eggs. The eggs are made in sex organs called ovaries. During sexual reproduction, the sperm and the egg join together. This is called fertilisation (the process of the gametes joining together). A fertilised egg or zygote is produced. The fertilised egg divides many times to form a ball of cells. Soon it will grow into an embryo and eventually it will develop into a separate individual. The sperm is made in the testes. It has a long tail with a head at the top of it, there are millions of sperm in the testes. The head of the sperm contains enzymes. These help it to digest its way into the egg if it finds one. ...read more.


Meiosis is not a very common kind of cell division. It only happens in the reproductive organs (ovaries and testes) Meiosis produces "cells which have half the proper number of chromosomes". Such cells are also known as "haploid gametes". These cells are "genetically different" from each other because the genes all get shuffled up during meiosis and each gamete only gets half of them, selected at random. Comparing Asexual Reproduction with Sexual Reproduction: There are very few differences between sexual reproduction and asexual reproduction. They are as follows: * Asexual reproduction is producing new cells from the parent cell, by cell division, but sexual reproduction is the fusion of the male and female sex cells. * In asexual reproduction when new cells are formed, it is called the process of mitosis, but in fertilisation when the sperm and egg join together, a zygote is formed. It is called the process of meiosis. * Sexual reproduction produces a baby which is not exactly like its parents, but the asexual produces an exact copy of its parent (a clone) * Asexual reproduction produces an exact number of chromosomes. 1 ...read more.

    "To Clone or Not to Clone- That is the Question".

    4 star(s)

    After the birth of Dolly, scientists have been on a rampage, attempting to clone almost every animal known to man. Mules, Kittens, Boars, Piglets, Calves, Monkeys have been the first few among the many. As is obvious, science and human values almost always clash; some may say it is foreseeable.

    before continuing, in gap 2 the cell continues to grow and perform its synthesis of proteins.

  1. Investigation into the varies stages of mitosis

    Another explanation therefore is like anaphase the other stages are quite rapid and take roughly the same time as the pie charts and graph show there is only a small difference between them compared to that of prophase. Therefore prophase takes slightly longer because the cell draws the process out

  2. The first aspect I have chosen to investigate is the asexual reproduction of yeast ...

    [3, 6] Asexual reproduction (mitosis) takes place during fermentation where the cooled wort is ran through the fermenting vessels and the yeast is added. Fermentation then takes place (explained later) during fermentation yeast reproduces by budding. Budding is an asexual reproductive structure.
